Step 9: Terminate the Unused End of the Cable
Terminate the unused end of the Enphase Q Cable (See Figure 4-6).
Remove 13 mm ( 0.5 inch) of the cable sheath from the conductors. Use the terminator loop to measure 13 mm.
Slide the hex nut onto the cable. There is a grommet inside of the hex nut that should remain in place.
Insert the cable into the terminator body so that each of the two wires land on opposite sides of the internal
separator.
Insert a screwdriver into the slot on top of the terminator to hold it in place and use a 27 mm wrench or channel
lock pliers to tighten the hex nut to 7 Nm.
Hold the terminator body stationary with the screwdriver and turn only the hex nut to prevent the conductors
from twisting out of the separator.
Turn only the hex nut to prevent conductors from twisting out of the separator.
Attach the terminated cable end to the PV racking with a cable clip or tie wrap so that the cable and terminator do
not touch the roof.
Figure4-6. Terminate the Unused End of the Cable
The terminator cannot be reused. If you unscrew the nut, you must discard the terminator.
Step 10: Install an AC Junction Box
The Enphase Microinverter works with single-phase 230 VAC service.
A)Verify that AC voltage at the site is within range:
Single-Phase
Three-Phase
L1 to N
207 to 253 VAC
L1, L2 to L3
360 to 440 VAC
L1, L2, L3 to N
207 to 253 VAC
B) Install a junction box at a suitable location on the racking.
C) Provide an AC connection from the junction box back to the electricity network connection using equipment
and practices as required by local jurisdictions.
